OctoberBass RCA-4 First Build

[wazkelly]

I put a Guitar Fetish MM PUP in my MMB4 and thought is was only 3 wire.

2 Ground wires sounds weird unless you are referring to something like a braid or shield plus the inner?

Did the PUP come with wiring instructions?

Cheers, Waz

Yes Waz, a braided copper wire, black, white and red. The white is taped off till I find a coil split/Master volume pot to add to this build. Or some other option. The 3 way in middle position is kinda... eh, but new pots and switch may be the way to go. Otherwise, up switch, or down switch really ROXKS! I got 2 rehearsals tomorrow and I'll put it through the paces.
And THANK YOU for all the advise getting me through all this!

Maybe swap the red for white and see if that makes a difference. Sometimes wire colours don't make sense and the white might just be the 'hot' wire.

In fact, the more I think about it these are Humbuckers and both are probably hot wires for each coil and therefore if not coil splitting maybe try soldering both on the same lug? Most 4 wire guitar HB's have red & white soldered together to complete the circuit and separated if doing coil splits.
